When converting 7.7 mgd into cfs, what is the correct result?

When converting 7.7 mgd into cfs, what is the correct result?

• A. 11
• B. 12
• C. 15
• D. 19

Answer: (B)

To convert million gallons per day (mgd) to cubic feet per second (cfs), it is essential to use the correct conversion factors. First, understand the relationship between the units: 1 million gallons is approximately equal to 3,785.41 liters. In the case of water, 1 gallon can also be converted to cubic feet. Specifically, 1 gallon is about 0.133681 cubic feet. With this knowledge, let's break down the conversion step by step: 1. Start with the value in mgd, which is 7.7 mgd. This means 7.7 million gallons per day. 2. Convert million gallons to gallons: 7.7 mgd = 7.7 x 1,000,000 gallons/day = 7,700,000 gallons/day. 3. Now convert gallons to cubic feet: Multiply the gallons by the cubic feet conversion factor: 7,700,000 gallons/day × 0.133681 cubic feet/gallon = approximately 1,030,575 cubic feet/day. 4. Next, convert the daily rate into a per second rate, since there are 86,400 seconds in a day (24 hours x

With this knowledge, let's break down the conversion step by step:

1. Start with the value in mgd, which is 7.7 mgd. This means 7.7 million gallons per day.

2. Convert million gallons to gallons:

7.7 mgd = 7.7 x 1,000,000 gallons/day = 7,700,000 gallons/day.

3. Now convert gallons to cubic feet:

Multiply the gallons by the cubic feet conversion factor:

7,700,000 gallons/day × 0.133681 cubic feet/gallon = approximately 1,030,575 cubic feet/day.

4. Next, convert the daily rate into a per second rate, since there are 86,400 seconds in a day (24 hours x
